Light-Matter-Coupling formalism for magnons: probing quantum geometry with light
Ying Shing Liu, Emil Viñas Boström, Michael A. Sentef +1
Nontrivial quantum geometry is a key feature of the wavefunctions of collective magnetic excitations in topological systems, but accessing it experimentally remains an open challen…

Broadband THz spectroscopy system beyond 25 THz using BNA crystals and a tunable single-ring-fiber compressor
Wei Cui, Aswin Vishnuradhan, Markus Lippl +4
We present a terahertz time-domain spectroscopy (THz-TDS) system which accesses a broadband spectrum, efficiently covering the so-called "new THz gap" between 5 and 15 THz and exte…
